Problem

Issue Type: Bug Hi, After my VS Code updated to the latest version for some reason i can no longer place a breakpoint anywhere in my code. When i place a breakpoint, it gives the round circle without red and it says "Unbound breakpoint". This is a little bit disappointed. Below is the launch.json configuration: { // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "type": "chrome", "request": "launch", "name": "Chrome - CIS5", "url": "https://localhost:3000", "webRoot": "${workspaceFolder}", "sourceMaps": true, "sourceMapPathOverrides": { "webpack:///./": "${workspaceRoot}/" } } ] } VS Code version: Code 1.47.0 (d5e9aa0227e057a60c82568bf31c04730dc15dcd, 2020-07-09T08:02:06.629Z) OS version: Windows_NT x64 10.0.17763 <details> <summary>System Info</summary> |Item|Value| |---|---| |CPUs|Intel(R) Core(TM) i7-7820HQ CPU @ 2.90GHz (8 x 2904)| |GPU Status|2d_canvas: enabled flash_3d: enabled flash_stage3d: enabled flash_stage3d_baseline: enabled gpu_compositing: enabled multiple_raster_threads: enabled_on oop_rasterization: disabled_off protected_video_decode: enabled rasterization: enabled skia_renderer: disabled_o
